| Abstract | ||
| In order to achieve up to 1 Gbps peak data rate in future IMT-Advanced mobile systems, Carrier Aggregation (CA) technology is introduced by the 3GPP to support very-high-data-rate transmissions over wide frequency bandwidths up to 100 MHz in its new LTE-Advanced standards [1]. This technique makes it possible for multiple spectrum bands to be utilized by the same user in order to satisfy the large bandwidth demand of the service and achieve better performance [2]. This paper provides an overview of carrier aggregation and discusses major technical issues including aggregation structure, scenarios and CA implementation in LTE-Advanced systems [3]. A simulation model of LTE-Advanced in the downlink is developed to investigate the impact of intra-band contiguous CA using up to two Component Carriers (CCs) on the system performance in terms of throughput [4]. The throughput increases from 5.152Mbps to 88.688Mbps when the bandwidth increases from 1.4MHz to 20MHz and when we aggregated two CCs each one with 20MHz, the throughput increased from 88.688 Mbps to 168.816Mbps and the bandwidth because 40MHz. The carrier aggregation is technologically feasible and can be used to significantly increase LTE-A peak data rates. | ||
